Try deleting/forgetting the 2.4 in the tv settings. If it can't connect to the 2.4 --- if the 5 is the only ssid it knows --- it should stay on the 5. No such problems here. Connected solid to my Netgear RAX45 router 5 GHz, 960 Mbps link. They're about 9' apart. You might need a wi-fi extender or Mesh network.
